Chapter 140: What I’m best at After hearing Su Chen's words, the little girl pulled over her schoolbag and took out two long strip magnets the size of a whetstone. ░▒▓█►─═ ═─◄█▓▒░ There are also two round electromagnets with plastic shells. "No, this is just these two dollars. When I was in the hospital, my two grandfathers came to visit and gave it to me by the way." "They had a fight in the room to let me choose, and in the end I had to take all four." She put the magnet into Su Chen's hand and stared at Su Chen playing with it in confusion. Su Chen attracted the two natural magnets together, then pulled them apart to test their strength. Then, he shook his head with some disappointment: "The suction power is too small..." Putting down the natural magnet, Su Chen turned his attention to the electromagnet aside.
On the plastic shells of the two cylindrical magnets, basic parameters are posted, including maximum voltage, resistance, number of coil turns, etc. Su Chen lowered his head to sort out his thoughts: "With these data, we can make a rough calculation. The maximum magnetic induction intensity is equal to the product of the maximum current, the number of coil turns, and the vacuum permeability divided by the height of the cylindrical electromagnet..." "And the radiator valve and wrench at the murder scene are made of iron. Calculating the magnetic permeability of the iron and estimating their contact area... If you calculate it this way, the suction force is probably enough." "Brother, what are you mumbling about?" The little girl didn't understand what Su Chen was talking about. Su Chen patted her shoulder and said softly: "It doesn't matter if you don't understand it now. Study hard and you will learn it later." "······All right." The little girl obediently returned to her seat, took out the magazine in her schoolbag and started reading. Su Chen, who was sitting next to her, gradually became serious. Because if his guess is correct... So, the two old grandfathers that this little girl is familiar with are completely suspected of being the murderer. ······ at the same time. Platinum City, in a residential building south of Guangming Elementary School. Chen Kang took out the key, opened the door, and walked in carefully. However, before the old man with slightly frosty temples could close the door, a slipper flew over from the darkness. With a "pop" sound, he was slapped on the back of the head!
Accompanied by the cursing voice of an old woman: "Chen, you don't have this family in your heart, right? You guard your canteen every day, why don't you come back early?" "Hey!" Chen Kang covered his head and explained softly: "Honey, honey, listen to me. Isn't this the girl from Guangming Elementary School who is hospitalized? I'm going to visit you. You... eh eh eh!" Snap! Snap! Before Chen Kang finished speaking, a tough old woman rushed out of the room, the slippers in her hands clattering. He was dragged out of the living room and out the door. "Chen, you are right, right? How dare you argue? I'm too lazy to see you. You have no home in your heart, and you don't have to come back. Get out!" The old woman kicked Chen Kang out of the house, and then closed the door with a bang. Chen Kang was left wearing a hurdle vest and complaining outside the door. Ma De, that old man Zhao Ping is right, I am afraid of my wife... So what, that old bachelor still doesn’t have a wife? I win in every sense! Chen Kang felt a lot more balanced. He stood outside the door and quickly arranged his clothes, fearing that his miserable appearance would be seen. However, when he turned around, he found a woman in professional attire—his precious daughter—standing behind him, looking at him with surprise. "Dad, have you made my mother angry again?" The daughter sighed helplessly. She had to deal with this incident at home after working overtime. Chen Kang opened his mouth and was about to defend himself, but the old woman's words had already been shouted from the room: "Look at your father's potential! He's a big man, and he guards his shabby canteen every day. People who don't know it think there's gold in it!" Chen Kang:······ ······ Five minutes later, outside the community. Chen Kang and his daughter Chen Wei were sitting on the steps at the door of the building. "Dad, just wait a little longer, my mother's anger will soon dissipate." The daughter looked at her watch and said half-jokingly: "Dad, just listen to my mother. You really can't make much money from your canteen, and I don't expect you to buy me a house..." "To put it bluntly, you only have so much ability, so don't bother with it."
"No, no." Chen Kang stroked his non-existent beard and put on a sophisticated look: "Daughter, you are still smiling, do you know that in fact, most people can be called geniuses in a certain career?" "It's just that most people fail to find what they are good at, so they live their lives doing nothing." "Ah, for example, Su Chen, who is very popular in the live broadcast of chasing murderers. Wasn't he also an unknown clerk before joining the show? So, your father and I are actually capable, but they are just buried... ····” "Dad, please save it." Her daughter just thought that he wanted to regain face in front of her, and smiled with disbelief on her face: "I've been with you for nearly thirty years, and I haven't seen what you're good at..." "Don't laugh, I'm serious!" Chen Kang looked at her helplessly: "Dad doesn't have any abilities..." He suddenly raised his head, looked at the sparse and bright stars in the sky, and said softly: "It can be said that there is one thing. In the entire Dragon Kingdom, I am the only one who can do it. It has been decades and so far, no one can do it better than me." "Oh? Dad still has this ability?" Her daughter was amused by Chen Kang's pretentious manner, she covered her mouth and said: "What is it?" "Open a canteen?" "wrong." "You're pretty good at catching mice, although it's useless." "No." "Dad, please stop showing off. Don't let it be what you imagined..." Chen Kang suddenly smiled and said to his daughter: "I just gave birth to you and raised you. Who else in the world could have such a precious daughter!" "Hahahahaha!" Daughter Chen Wei:······ Here Chen Kang is laughing loudly. Suddenly there was a harsh braking sound from the side. Immediately afterwards, a thin young man riding a motorcycle with colorful light tubes jumped out of the car and shouted to Chen Kang:
"Lao Deng, I will stop my ghost fire next to your broken electric. Is it safe?" After that, he also gave his daughter Chen Wei a fashionable wink. Chen Kang:······ Chen Kang's face suddenly drooped, and he glanced at the will-o'-the-wisp young man irritably: "I advise you not to stop. It will affect your height." "Just kidding, what impact can it have?" The will-o'-the-wisp young man propped up his stick and patted the unhappy Chen Kang. "Because I'll break your legs!" Chen Kang went up and kicked him: "I'm warning you kid, stay away from my daughter!"
